Application filed June 14,

To all whom it may concern:

Be it known that I Gnonon CLnMENrs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Vacuum-Cleaners, of which the following is a specification.

y invention relates to improvements in vacuum cleaners and has for one of its principal objects to provide means for simultaneously disconnecting the suction nozzle and connecting a suction hose with the pumping chamber.

It is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation with parts shown in section; v I

Fig. 2 is a side elevation with the suction hose connected; 1

Fig. 3 is a bottom plan view of a portion of the structure illustrated in Fig. 1;

Fig. 4 is a cross section along the line 4-4 v of. Fig. '3.

v cap A". The

Like parts are indicated by the same letter is all the figures.

A is a fiat c lindricalcasing, the interior of whichI call the pumping chamber and in it rotates the'fan or pumping device A A is the dischar e outlet therefrom tanntially arrange The motor casing A 1s attached to one side of the fan casing, and preferably integral with the latter is the suction. chamber A communicating therewith through the port A and provided with the screw-threaded passageway A closed by the suction passage A connects with the suction chamber A 'at one end and at the other extends into an elongated narrow suction nozzle A, the outer lip of which is preferably provided with the inclined grooves or corrugations A A is a spring clip which removably engages the inner lip of the suction nozzle andcarries the soft squeegee A projecting outwardly from the nozzle. The pump casing A is pivotally mounted on an eccentric axis between the forks B on thehandle B and islimited in its rotational movement b the lugs B placed on the same side 0% the center of gravity as the axis of rotation so that the pum casing and its associated parts may be tilted forwardly and downwardly but not be permitted to proceed too far in that direction. The conductors B lead from the mo- VACUUM-CLEANER.

tor to the controlling switch B on the handle,'from which switch leads the flexible conducting wire Bilwhich is shown in Fig.

1 as wound about t e hooks B on the handle B.

The dust receiving bag C is removably attached to one end of the tan ential discharge way A and at the other en is closed by the spring clip C which is supported b means of the spring C from the handle D is a hose tube provided with a screwthreaded portion D to engage the screwthreaded port A in the wall of the suction chamber, an extension D which passes through the suction chamber and is received into the port A, and a projecting end on which the hose D is adapted to be attached. When the hose tube is removed, the cap A is substituted therefor and the hose'tube may be screw-threaded into the outlet so as to deliver air under pressure if desirable.

It will be evident that while I have shown in my drawing anoperative device, many changes might be made in size, shape and arrangement of the several parts without departing materially from the spirit of my invention.

The use and operation of the invention are quite obvious.

When it is to be used for cleaning floors in the usual manner, .the hose tube is removed and the cap A applied to close the port A. The wire cable is removed from the hooks and the proper connection made, whereupon the motor is set in operation to drive the fan or pump and suck the dust up through the suctlon nozzle discharging into the bag G, whence the air escapes, leaving the material to be collected behind.

When the device is to be used for wood or other smooth or hard floors, the'removable squeegee is attached.

When the hose used the istobe cap A is removed and the hose tube If the device is to be used for delivering 1 air under pressure, the hose tube is'sorewthreaded into position inthe discharge way as indicated in dotted lines in Fig. 2.

I claim:

1. A vacuum cleaner consisting of a casing provided with a pump chamber and a suction chamber and separated therefrom by a dividing wall provided with an opening, the walls of the suction chamber terminating in a suction nozzle and the suction chamber provided with an opening registering with the opening in the dividing wall and adapted to receive a cap for closing it or a hose tube extending into the inner opening. 1

2. A vacuum cleaner comprising a pump chamber, a suction chamber, having an outlet opening to the pump chamber, a suction nozz e and an inlet opening, and a removable closure therefor, said openings adapted to receive a connecting inlet tube.

3. In a pneumatic cleaner, a casing having a fan chamber, a suction chamber arranged directly below said fan chamber and separated therefrom by a dividing wall provided with an opening, said suction chamber being provided with an opening in the bottom thereof in line with the opening in the dividing wall, and a coupling member adapted to be secured in the opening in the bottom of the suction chamber and having a tubular extension which extends across said suction chamber and into the opening in the dividing wall between said suction chamber and the fan chamber.

4. A suction chamber having a fan chamber and a second chamber adjacent to said fan chamber and separated therefrom by a dividing wall provided with an opening, said second chamber being provided with an opening in the wall thereof opposite the opening in the dividing wall, a coupling .member adapted to be secured in the opening in the second chamber and having a tu bular extension adapted to extend across said second chamber. in operative relation to the o enin in said dividing wall, and a cover a apte second chamber when said coupling member is removed;

5. In a pneumatic cleaner, a casing havto close the opening in said' ing a pump chamber and a second chamber adjacent thereto and terminating in a cleaning device, there being an aperture dividing wall between said chambers and the outer wall of said second chamber having a supplemental opening adapted to receive either for closing it or a coupling c0mmuni-- a cap cating immediately with the aperture in the dividing wall.

6. A suction cleaner having a pump chamber and a second chamber separated therefrom by a dividing wall provided with an opening whereby the second chamber may communicate with the first mentioned chamber, the second chamber having an inlet mouth and an opening in operative relation to the opening in the dividing wall, and a coupling member adapted to be applied to the last mentioned opening and having an extension adapted to cut off communication between said first mentioned opening and said inlet mouth.

7. In a cleaner, a casing having a fan chamber, and a suction chamber adjacent thereto and separated therefrom by a dividing wall provided with an opening, said suction chamber communicating with an operating mouth and the wall of said suction chamber having a removable portion, and a hose connection adapted to be secured in direct communicating relation to said opening when said removable portion is displaced.

8. In a vacuum cleaner,.the combination of a casing with a nozzle attached thereto, a

' suction pipe leading therefrom and a suction hose attachment adapted to simultaneously cut off the nozzle connection and connect the hose with the suction.

9. A vacuumeleaner comprising a suction chamber having an oblon primary suction inlet and a secondary circu ar suction inlet, a pump chamber having a circular inlet from the suction'chamber the two circular inlets in substantial alinement, a removable cap for the secondary inlet and a removable inleading tube for the pump chamber adapted to connect the two circular inlets.

10. A vacuum cleaner comprising a suction chamber having a primary suction inlet from the suction chamber means for closing the secondary inlet and pump inlet leading means adapted to connect the pump inlet with the secondary inlet when the closing means is removed and thus disconnect {)lze suction chamber from the pump cham- GEORGE O LEMENTS.
